1. 31. Modelling 3D-woven composites on the macroscale: Predicting damage initiation and inelastic phenomena

   Författare :Carolyn Oddy; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D-woven composites; Anisotropy; Inelasticity; Damage initiation;

   Sammanfattning : Composites with 3D-woven reinforcement have been slowly making their way into different industries. The interlacement of yarns, not only in-plane but also through-thickness, means that in many applications 3D-woven composites can outperform their laminated counterparts. LÄS MER

3. 32. Towards a Viscoelastic Model for Phase Separation in Polymer Modified Bitumen

   Författare :Jiqing Zhu; Niki Kringos; Jean-Pascal Planche; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer modified bitumen; storage stability; viscoelastic phase separation; PMB model; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : In this thesis, a review is given on the most popular polymers used today for polymer modification of bitumen. Furthermore, the development of a model for phase separation in polymer modified bitumen (PMB) is proposed, that will enable a better control and understanding of PMB phase behaviour, allowing thus to enhanced long-term performance.

4. 33. Ensembles and Open Quantum Systems in Polaritonic Chemistry

   Författare :Eric Davidsson; Markus Kowalewski; Gerrit Groenhof; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polaritonic Chemistry; Open Quantum Systems; Cavity QED; The Jaynes-Cummings Model; Optical Cavities; Computational Quantum Dynamics; Theoretical Physics; teoretisk fysik;

   Sammanfattning : Optical cavities are structures where excitations in the electromagnetic field (photons of light) are confined and generally long-lived. The spatial confinement will enhance interactions with any matter systems in the cavity, such that the behaviour of a combined system is best understood in terms of polaritonic states; mixtures of excitations in both light and matter.

5. 34. Macroscale Modelling of 3D-Woven Composites: Inelasticity, Progressive Damage and Final Failure

   Författare :Carolyn Oddy; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D-woven composites; Anisotropy; Damage; Inelasticity; Phase-field; Failure;

   Sammanfattning : Composites with 3D-woven reinforcement have been slowly making their way into different industrial applications. The interlacement of yarns, not only in-plane but also through-thickness, means that in many applications 3D-woven composites can outperform their laminated counterparts. LÄS MER

7. 35. Ductile Failure in High Strength Steel Sheets

   Författare :Oscar Björklund; Larsgunnar Nilsson; Odd-Geir Lademo; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Developments in computer-aided engineering and the rapid growth of computational power have made simulation-driven process and product development efficient and useful since it enables detailed evaluation of product designs and their manufacturing processes. In the context of a sheet metal component, it is vital to predict possible failure both during its forming process and its subsequent usage. LÄS MER
